What is the cause of engine knocking?
The knocking sound often occurs when the air-fuel mixture is incorrect, which causes the fuel to burn in uneven pockets rather than uniform bursts. Left untreated, it can cause damage to the piston and cylinder wall. A knocking sound can also be caused by a lack of lubrication in the upper cylinder head area.2 Dec 2015
Can you drive a car with a knocking engine?
If you actually do have an engine knock and plan to later rebuild the engine that you have, continuing to drive the car could result in a rod coming loose and coming through the block. That will increase your repair costs because you will have no core to trade-in when you buy a new or rebuilt block.7 Feb 2012
